Abstract: In a subcutaneous microphone used in medical devices, a structure is introduced that constrains the motion of the diaphragm during normal operation of the microphone. In one embodiment, a raised portion, such as a pole or pillar is placed in the chamber at the middle of the diaphragm. The raised portion may contact one or both of the bottom surface of the chamber and the underside of the membrane, and generally acts to reduce the amount of deflection experienced by the membrane.

IPC: H04R25/00
Abstract: An external portion of an auditory prosthesis includes an external magnet that interacts with an implantable magnet to hold the external portion against the skin. Magnetic force generated by the stray field of these magnets can disturb the operation of a vibrating element of the auditory prosthesis. The technologies described herein utilize additional magnets disposed within portions of the auditory prosthesis to redirect the magnetic flux, which allows the vibrating element to be disposed more closely to the magnets, reducing the overall height profile of the prosthesis.

Abstract: An inductance communication coil, including a conductor having at least one conductive turn, wherein a width of the conductor is wider at a first location relative to that at a second location. The conductor can be made out of metal. In some embodiments, the first location and the second location are on the same turn. In some embodiments, the conductor includes a plurality of turns, wherein the first location is at a first turn and the second location is at a second turn.

Abstract: Disclosed examples generally include methods and apparatuses related to microphone units, such as may be found in implantable medical devices (e.g., cochlear implants). Microphone units generally include a microphone element connected to a chamber having a concave floor with the chamber covered by a membrane. Microphone units can be configured to produce an output based on pressure waves (e.g., sound waves) that reach the membrane. In an example, a microphone unit has a pressurized gas within the chamber below the membrane such that, while in a static state, the membrane deflects away from the chamber floor.

Abstract: A passive vibration cancellation system manufactured of a plurality of waterproof diaphragms and a more rigid support structure is sized to cover a microphone of an auditory prosthesis. The system includes multiple flexible diaphragms that deform in opposite directions when acted upon by sound, but deform in the same direction when acted upon by vibrations. The system can further include a collar or other compliant element to help secure a microphone assembly into the auditory prosthesis housing, while further reducing vibration transmission between the housing and the microphone.
